Perhaps related to this issue, I have also noticed that sometimes when I (re)boot my computer in the evening when Night Light is in an early stage, it remains stuck in that initial level of orange set after boot, and it doesn't gradually increase like it should do. Disabling and enabling Night Light then makes it work again.
As with the issue of Night Light being stuck after unlocking my machine in the morning, there is no way to manually trigger the behaviour, and it also doesn't happen all the time, which makes it very hard to debug. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2066902 Title: Night Light occasionally gets stuck Status in Mutter: New Status in mutter package in Ubuntu: Triaged Status in mutter source package in Noble: Triaged Status in mutter source package in Oracular: Triaged Bug description: [ Impact ] Since installing Ubuntu 24.04, every now and then Night Light gets stuck when my screen is locked at night and I unlock it in the morning. The screen is then very orange (more so than normally is the case with Night Light), and disabling it with the button in in the top bar menu does nothing. The only ways to restore the screen to normal are disabling and enabling the colour profile or running `gdbus call -e -o /org/gnome/SettingsDaemon/Color -d org.gnome.SettingsDaemon.Color -m org.gnome.SettingsDaemon.Color.NightLightPreview 1` [ Test Plan ] Unknown. Requires OP verification. [ Where problems could occur ] Night light and colour profiles are one in the same feature so touching one always risks affecting the other. Since all such gamma changes get committed along with other screen updates, there is the risk (particularly with atomic mode setting) that a mistake in any one change will cause the entire screen update to fail, resulting in black frames. [ Other Info ] I have never been able to find anything remotely relevant in any system logs regarding this issue. It also does not happen every day, but probably once every seven to ten days or so. My PC has an AMD RX550 GPU using the amdgpu driver. I'm not sure if it makes a difference, but so far I've not seen this problem on my other machines with Intel IGPs.
